Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

Plums varieties Jubileum, Excalibur and Reeves were harvested at commercial harvest date. After harvest fruits were dipped in hot water (56 °C) for 2 minutes then they were cooled down in cool water. Fruits were stored for 4 weeks in normal atmosphere (NA) and modified atmosphere (MAP) in xtend packaging film. In equilibrium state,modified atmosphere consisted of 10 % of O2 and 10 % of CO2. Excalibur contained the highest amount of total phenols, followed by Jubileum and Revees, while Jubileum had the highest antioxidative potential (AOP) followed by Excalibur and Revees. Significantly more total phenols was found at second week of storage followed by forth week and after harvest. On the other hand, Revees contained significantly more flavonoids, followed by Excalibur and Jubileum. The highest antioxidative potential was found immediately after harvest followed by that of 4 weeks storage and finally that of 2 weeks storage time. Significantly more flavonoids were found at the beginning of storage and least at the end of storage. Plums stored in modified atmosphere had the highest AOP, followed by NA, MAP hot water (HW) treated and NA hot water treated fruits. With regard to storage conditions, more flavonoids were found in NA stored plums, followed by MAP HW, MAP and NAHW. Revees had the highest polar AOP followed by Jubileum and Excalibur, but no statistically significant differences were found. Also the highest polar AOP was found in forth week of storage again no statistically significant differences were found. Storage atmosphere gave no statistically significant differences in polar AOP. Results showed that storage conditions influence the AOP, total phenols and flavonoids. Flavonoids are more abundant after harvest, total phenols in the middle of storage period. Hot water treatment is becoming popular because might be used for organically grown fruits and vegetables. In our experiment hot water treatment showed e tendency to decrease AOP, flavonoids and polar AOP but significantly decreases total phenols.
